Between 1967 and 1971 Rose Simpson lived with the Incredible String Band (Mike Heron, Robin Williamson and Licorice McKechnie), morphing from English student to West Coast hippie and, finally, bassist in leathers. The band's image adorned psychedelic posters and its music was the theme song for an alternative lifestyle.

Rose and partner Mike Heron believed in, and lived, a naive vision of utopia in Scotland. But they were also a band on tour, enjoying the thrills of that life. They were at the center of “Swinging London” and at the Chelsea Hotel with Andy Warhol's superstars. They shared stages with rock idols and played at Woodstock in 1969. Rose and fellow ISB member Licorice were hippie pin-ups, while Heron and Robin Williamson the seers and prophets of a new world.
